摘　　要：城市化进程的加速给市政给排水管网的工作带来了巨大压力,传统的市政给排水管网检测修复技术较落后,无法满足新需求。文章基于对当前市政给排水管网缺陷的分析,提出了一种融合故障准确定位与非开挖修复的技术。利用该技术,可以检测外力破坏、管压极限破坏和腐蚀破坏的故障点,采取针对性的修复措施,最后通过实例进一步验证了这种非开挖检测修复技术的有效性。The acceleration of urbanization has brought great pressure to the work of municipal water supply and drainage pipe network.The traditional detection and repair technology of municipal water supply and drainage pipe network is relatively backward and can not meet the new needs.Based on the analysis on the defects of the current municipal water supply and drainage pipe network,this paper proposes a technology that integrates accurate fault location and trenchless repair.By using this technology,the fault points of external force damage,pipe pressure limit damage and corrosion damage can be detected,and targeted repair measures can be taken.Finally,the effectiveness of this trenchless detection and repair technology is further verified through examples.
